Calibrate radio controlled watch or clock at anytime, anywhere
Clock Wave allows you calibrate radio controlled watch or clock anytime and anywhere. Just click "Transmit" button, set your watch or clock to manual receive time signal, and place it nearby your iPhone/iPad's speaker, it will be calibrated in a few minutes.
Clock Wave features:
- Covers 5 major longwave time signal stations all over the world.
* USA: WWVB
* Japan: JJY
* China: BPC
* UK: MSF
* DE: DCF77
- Automatically transmit the accurate time.
* If your radio controlled watch/clock doesn't support station BPC, select station JJY manually to use in China.
* If your radio controlled watch/clock doesn't support station MSF, select station DCF77 manually to use in UK.
* If your radio controlled watch/clock support only a specified timezone or station, (e.g. Using a radio controlled clock support only JJY station in Australia.), select the watch/clock timezone manually in app settings.

The REAL Deal; you won’t be disappointed
I’m an engineer, so I was a little skeptical. Today the clocks changed over from daylight savings and I had a choice: set my Citizen manually or try Clockwave. Either way I had to pull up the manual since I’ve only had my JDM watch for 6 months and l’ve only had to set it once (which was a little bit of a pain since I did it manually, and it was still on Tokyo time when I received it).
Anyway, I read from another post to keep Clockwave set at JJY, rather than auto select (since my watch only receives the radio signal in Japan). For the record, I’m in EST and the app is showing UTC +09, (JST,KST). I started the app and heard a little clicking with the volume full up on my iPad. I depressed the A button on my Citizen for 2 seconds, and the second hand swept to RX; in just a few seconds it moved to the H position showing good signal strength. Five minutes later my watch was set correctly & was spot on when I compared it to Atomic Clock.
Kudos to the developer.
I downloaded this very skeptical!! Already expecting it not to work! Because it makes sense right how can a phone that can only transmit sound set a clock that receives radio signals! I don’t know how this works but it truly does! However you have to hold your clocks receiver close to the speaker on your phone with the volume all the way up! Then be patient it after you start a manual receive your signal reception will show very strong then just minutes later you will have a set clock! It’s really pretty amazing!!! The key to this working is keeping the clock your setting close to you phone while your transmitting!! Otherwise it won’t work!! You can’t believe those that say it doesn’t work because it really does!!
I was doubtful of how clicking sounds from a speaker would simulate radio signals but bought the app anyway. I tried the app with a Lacrosse atomic clock that can’t receive a WWVB signal unless it was by a west facing window. It didn’t work so I was all set to give a 1 star scam rating and review.
I decided to try it again but this time I aligned the speaker with the back of the clock and turned up the iPad volume. When I looked five minutes later the signal received icon was showing on the clock and it was synchronized with the correct time, having been 12 seconds slow before.
Now I have to find how why and how this works
